Vitalik Proposes the Extremely Lean Consensus Chain
Vitalik Buterin has proposed a redesign of Ethereum's consensus chain that cuts per-validator state to just 6 bytes by removing pubkeys from beacon chain state, replacing them with deposit tree indices, and shifting all balance accounting to daily STARK proofs that validators generate and submit themselves. This eliminates end-of-epoch processing entirely and could scale the validator set to millions. A second phase adds strong privacy by having validators generate a fresh pubkey each day, completely re-anonymizing their on-chain identity, with only effective balance and slashing status revealed through the daily proof.
